Step 1

Preheat your oven to 350 degrees Fahrenheit. Spray a 9x13 baking dish with baking spray and set aside.

Step 2

In the bowl of a stand mixer using the paddle attachment, cream the butter, oil, and sugar until pale and fluffy, about 4-7 minutes.

Step 3

Add the eggs and egg yolks, one at a time, beating on medium-low (a setting of 3-4 on your stand mixer) after each addition. Add vanilla and beat on medium until combined.

Step 4

In a separate medium mixing bowl, sift together flour, salt, and baking powder. Add cinnamon and nutmeg and whisk ingredients to combine.

Step 5

Alternate adding some of the flour mixture and some of the buttermilk into the bowl with the butter and sugar mixture, starting and ending with the flour. Mix batter on medium speed (4-5 on stand mixer) after each addition.

Step 6

Scrape down the sides and bottom of the bowl and give everything one more mix on medium (a setting of 4-5 on your stand mixer) until you see no more flour in the batter. Be careful not to overmix your batter.

Step 7

Fold in pecans with a silicone spatula until evenly mixed into the batter. Pour batter into your prepared baking pan and bake for 35-45 minutes, or until a toothpick or skewer inserted into the center comes out with only a few moist crumbs.

Step 8

About 5 minutes before you remove the cake from the oven, melt butter in a medium saucepan over medium-high heat. Add pecans and cook until butter is frothy and begins to brown, stirring constantly. Continue to cook until the butter is a golden brown and the foam begins to subside a bit. This process should take about 6-8 minutes.

Step 9

Remove the pan from heat and stir in the sweetened condensed milk. Continue to stir until the condensed milk is completely mixed in with the butter and the sauce is smooth and coats the back of a wooden spoon.

Step 10

Remove the cake from the oven and allow it to cool for about 5 minutes in the pan. Poke several holes into the warm cake with the back of a wooden spoon and pour warm praline sauce over top. Smooth sauce out over cake with a silicone spatula, getting it into all of the holes.

Step 11

Slice and serve the cake warm. Enjoy!
